Ill/GROVE]; ALARM-ATTACHMENT FOR S'il'lilhlhS.

The Schedule referred to in these Letters Patent and making part of them me.-

To whom it may concern:

' Be it known that I, J 01111 G, LEISTNER, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Distilleries and I hereby.de-

clare the following to bea full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this specification.

My improvement consists in the applicationvof an alarm-whistle to the tail-pipe ofa distillery-worm, so as to give notice of the instant that the high-wine -vapor begins to come over from the flake-stand.

The accompanying drawing is an elevation of a disfilling-apparatus, provided with my improvement.

A is the still.

B, the doubler.

O, the low-\vinetub. V

D, the credit or low-wine meter.

E, the low-wine receiver.

F, the flake-stand or worm-tub.

G, the tail of the worm, leading into the debit or high-wine meter H." I p The parts above described may be-of the represented or any approved construction, and require no specific description.

In order to avoid the accumulation of high-wine in the worm, with the consequent danger of bursting the pipe,.or of driving the distilled vapor back into the low-wine vessels, 1 connect to the topof the tail-pipe G, a siphon, I, whichterminates in a whistle, J, which, the moment that high-wine begins to pass over, gives, by its sound, warning'of the fact, and thus enables the attendant to open and close the proper cocks, and thus save both the pure spirit, and guard the apparatus from danger of explosion; and it also, by keeping all the parts duly-open, at the proper time, prevents the settling and freezing of the contents of the tail-pipe in' cold weather.

My whistle is also useful hy'indicating an excess of steam in the still, which excess is liable to wastespirit by pushing the distillation to a speed beyond which it can be properly and fiilly condensed, and should the tail-pipe become frozen between the heats, the silence hand JOHN G.
